问题描述
我希望我错过了一些愚蠢的事情.
I hope I'm missing something silly.
我正在尝试使用OpenShift的免费托管服务上的PHP 5.4卡盒在Apache 2.2上使用.htaccess重定向URL.
I'm trying to redirect URLs using .htaccess on Apache 2.2 using the PHP 5.4 cartridge on OpenShift's free hosting service.
这与URI/permalink/a123匹配(请注意，规则的过滤器模式中没有前导斜杠):
This matches the URI /permalink/a123 (note the lack of leading slash in the rule's filter pattern):
RewriteEngine On
RewriteRule permalink/a.*$ /permalink/b [R=301,L]
这与URI/permalink/a123不匹配(请注意规则过滤模式中的斜杠):
This does not match the URI /permalink/a123 (note the leading slash in the rule's filter pattern):
RewriteEngine On
RewriteRule /permalink/a.*$ /permalink/b [R=301,L]
那我到底有什么愚蠢的错误?
So what stupid thing do I have wrong?
谢谢.
推荐答案
用于匹配RewriteRule中的模式的URI在每个目录上下文中(在htaccess文件或<Directory>容器中)被规范化.通过删除开头的/.因此，如果请求的URL是:
The URI used to match patterns in a RewriteRule are canonicalized in a per-directory context (either in an htaccess file or in a <Directory> container) by removing the leading /. So if the requested URL is:
http://example.com/web/permalink/123
在文档根目录的htaccess文件中，用于匹配规则的URI为web/permalink/123.但是在web文件夹中的htaccess文件中，URI是permalink/123等.
And from within an htaccess file in the document root, the URI used to match rules is web/permalink/123. But within an htaccess file in the web folder, the URI is permalink/123, etc.
因此，您不能让模式以/开头，因为它们是在htaccess文件的上下文中从URI中剥离的.
Thus you can't have your patterns start with a / because they're stripped from the URI in the context of an htaccess file.
